I understand you have questions in regard to Intel® Turbo Boost Technology, let me help on this matter.Since ESXi has been developed for server platforms, I assume your current configuration is based on server computers.1. The Intel® Turbo Boost Technology works depending on the workload of the processor, whenever the program requires speeding up the processor speed it will throttle to the maximum allowed.https://www.intel.com/content/www/us/en/support/articles/000005641/processors.html

2. This is the same answer as the previous response.

3. We think you have a server environment and this will required especial cooling equipment but the technology does not work just when the processor reaches maximum processor temperature. You can check maximum temperature at https://ark.intel.com/

4. It does not work of power limits or temperatures. This will work depending on the processor workload. Please see the information that was linked previously.
